CHAS. PERLEY, OF NEW YORK, N. Y.

CHAIN-LOCKER PIPE.

specication of Lettersratent N6.

To all whom 'it may concern:

Be it known that I, CHARLES PERLEY, of the city, count-y, and State ofNew York, have invented and made a new and useful Improvement inChainLocker Pipes for Vessels; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawing,making part of this specification, wherein- Figure 1, is a plan of thechain locker pipe as with the cover removed. Fig. 2, is a verticallongitudinal sect-ion. Fig. 3, is a cross section at line 1, 1, of Fig.1, and Fig. 4, represents the under side of the locking piece.

The like marks of reference denote the same parts in all the figures.

The pipes in general use passing through the deck of vessels to conveythe chain cable into the locker, are formed as a simple metal pipe andflanch rising slightly above the deck; the result is t-hat water veryoften runs down into said chain lockers, and also rats pass down thesame into the vessel, particularly when lying at anchor or fastened to awharf or dock, and besides this difliculty is experienced in holdingonto the extreme end of the chain and preventing the same droppingthrough into the chain locker below.

The nature of my invention consists in fitting thechain locker pipe witha hinged clamp or lock formed on its under side of a shape correspondingto the chain made use of, so that this locking piece when brought downonto the chain effectually holds the ,same from running back into thechain locker, and also allows the vessel to rideat anchor by the same,and being formed to receive the chain as it passes horizontally along onthe deck just before it passes down into the chain locker gives facilityfor applying a metallic or other cover that effectually excludes ratsand prevents the entrance of water, and by a small tow packing stuffedin around the chain, the said locker would be made perfectly water tighteven if the vessel was submerged, but the locking piece being formed tocoincide with the 13,760, dated November 6, 1855.

shape of the chain would be sufficiently watertight under ordinarycircumstances without said tow packing.

a, is a iianch attached to the deck.

Z), the opening through said deck to the chain locker. c, is a circularfianch formed on or with the flanch a, around said opening (b) and of aheight to correspond with the parts of the locking piece.

cl, is a metallic flanch or block extending out on one side of the pipe(b) and forlned with a groove 2, made iiaring at the outer end andcurved downward at the inner end so as to allow the chain c, to runfreely into or out of the chain locker.

On one side of the block el, I attach the locking piece f, by means of ahinge 3, so that it can be turned out of the way when the chain ispassing in or out, and when turned down into place a pin 4, is made useof passing through the side part or fianch d, and this pin 4, I alsomake use of as a lever to raise up the lock, by inserting the same inthe hole 6, provided for that pur pose. On reference to Fig. 4, it willbe seen that the under side of the locking piece f, is so shaped as tolit over and permanent-ly hold the chain e, in place, the chain beingshown by dotted lines. Thereby the chain cannot become detached, unlessdesired, without rupture of the parts, and in order to relieve the hinge3, and pin 4, of any unnecessary strain when the vessel is atanchor, Imake use of a square rib 5, entering a mortise in the flanch CZ. By thisconstruction of locking piece to receive the chain horizontally I amenabled to form the upper edge of the flanches d, and c, and lockingpiece f, of a uniform height so as to receive the cap g, sitting overand around the edges of said parts as seen in Figs. 2, and.

It will be thus seen that my chain locker pipe is simple cheap andeiiicient, dispensing when desired with separate cable Stoppers, orbitts by which the vessel rides atanchor, and accomplishing thebeneficial results heretofore specified.

What I claim and desire to secure by Letters Patent is- The lockingpiece f, constructed substantially as specified and applied to the chaintober, one thousand eghthundred and fifty ve.
